Benefits of technology

The present invention is about a device that can stimulate nerves effectively without causing any harm to the heart. It is designed for therapeutic purposes.

Problems solved by technology

In addition, it has been proposed that stimulation of the vagus nerve over a long period of time on a patient experiencing cardiac failure can potentially prevent progress of the disease.

Embodiment Construction

[0022]The nerve stimulation apparatus 1 according to an embodiment of the present invention will be described below, with reference to the drawings.

[0023]As shown in FIG. 1, the nerve stimulation apparatus 1 according to this embodiment is provided with electrodes 2 attached to a nerve N in the vicinity of a heart H, such as the vagus nerve etc., a cardiac-event detector 3 that detects an event in the heart H (cardiac event), a stimulation-pulse output unit (stimulation-signal output unit) 4 that outputs a stimulation pulse (nerve stimulation signal) to the nerve N through the electrodes 2, and a controller 5 that controls the stimulation-pulse output unit 4 on the basis of the cardiac event detected by the cardiac-event detector 3.

[0024]The cardiac-event detector 3 is provided with two or more indwelling detection electrodes 6 that are in contact with parts of the heart H (for instance, in the example shown in FIG. 1, the right atrium RA and the right ventricle RV), a signal detect...

Abstract

Provided is a nerve stimulation apparatus that is capable of performing effective nerve stimulation depending on a therapeutic purpose without adversely affecting a heart. Further provided is a nerve stimulation apparatus including: a stimulation-pulse output unit that outputs a stimulation pulse; a cardiac-event detector that detects a cardiac event; and a controller that controls the stimulation-signal output unit so as to output, during a cardiac refractory period, the nerve stimulation signal having an intensity that corresponds to the heart rate obtained on the basis of the cardiac event detected by the cardiac-event detector.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is based on Japanese Patent Application No. 2011-201949, the contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a nerve stimulation apparatus.[0004]2. Description of Related Art[0005]Stimulation of the vagus nerve on a patient who has experienced cardiac infarction has conventionally known to be capable of suppressing cardiac remodeling (for example, see WO2006 / 098996). In addition, it has been proposed that stimulation of the vagus nerve over a long period of time on a patient experiencing cardiac failure can potentially prevent progress of the disease.[0006]In the related art described above, in order to perform cardiac treatment on a patient, remodeling control therapy is performed by biventricular pacing, and anti-remodeling therapy is performed by nerve stimulation. In addition, by performing nerve stimulation in the ...
